Based on the carrying capacity of the habitat and the changes that occurred in number of the two snake species, correct option is They occupy the same niche and are competing fully for all resources; option D
<h3>What is carrying capacity of a habitat?</h3>
The carrying capacity of a habitat is the maximum number of species the available resources in that habitat can sustain.
The data given of the species of snakes, Species A and Species B, indicate that they are both present in the habitat after a change occurs in the habitat.
Since the population of Species A became zero after Species B was introduced in the habitat, they occupy the same niche and are competing fully for all resources.
In conclusion, the competition between the species of snakes is responsible for the decline in Species A.

Answer:
Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Explanation:
Answer: Two molecules of H2A
Explanation:
Structural organization of nucleosomes were determined by isolating them from unfolded chromatin and it has been found that the basic units of chromatin are the nucleosomes which consist of histone octamers of two molecule each of histone H2A and other histone molecules like H2B, H3 and H4. The histones are wrapped around with 147bp of DNA in almost two (2) turns.
